The feature of this disease was characteristized by hyper gammaglobulinemia,elevated serum IgG4 levels,the presence of autoantibodies against carbonic anhydrase and lactoferrin,a diffused intumescence on pancreas,prominent lymphocyte infiltration with fibrosis in the pancreas.

此病的特点为高球蛋白，IgG4升高，抗碳酸酐酶抗体和抗乳铁蛋白抗体的存在，弥漫性肿大的胰腺、显著的淋巴细胞浸润伴随纤维化，临床表现多样，经典的腹部CT表现为胰腺弥漫性肿大呈腊肠样，密度均匀，轻微强化，周边低密度囊状缘，对激素治疗敏感。

METHODS: The models of abdominal aorta transplantation were made with micro-surgery in rats. The recipients were divided into three groups: allograft control group, atorvastatin-treated group and isograft control group. Vascular intimal thickness in all of the groups was observed by histological examination. The expression of proliferation cell nuclear antigenl and α-smooth muscle actin were determined by immunohistochemistry. The content of nitric oxide was measured by nitrate reductase chromatometry.

建立大鼠腹主动脉移植慢性排斥反应模型，分为3组：异系移植对照组、异系移植治疗组和同系移植组，60d后对移植动脉行病理组织学检测，观察移植动脉内膜增生程度；并行免疫组织化学染色，检测移植动脉增殖细胞核抗原和平滑肌肌动蛋白的表达情况，行硝酸还原酶比色法测定移植动脉组织NO的含量。

The present paper covers a simple method for preparing urease from jack bean. In terms of the method, the total yield was 37. 1% and the specific activity was 43. 6 μmol ?min-1/ mg protein.

报道了以刀豆为原料制备脲酶的一种简便方法，其总收率为37.1％，比活达43.6μmol·min~(-1)/mg蛋白。

Fund Project: the National Natural Science and Technology Source Program, No. 2001DEA1006*Abstract: Number of neural stem cells is small. NSCs look like circle or ellipse with or without short neurite, with large nuclear-cytoplasmic ratio and deep karyotin. NSCs have no visible differences with other kinds of cells in appearance, and have no cell surface marker. Currently, there are mainly three aspects to identify NSCs: expression of specific nerve antigen, including nestin, Musashi, transcription factor, and cell adhesion molecules; self-renewal ability including single cell clone analysis, BrdU mark and S phase cell; the potential of multi-direction differentiation including immunocytochemical process and reverse transcriptase polymerase chain reaction.

由于神经干细胞的数量很少，从细胞形态来看神经干细胞为圆形或椭圆形，无或有较短的突起，核质比大，核染色较深，形态上与其它种类的细胞没有明显的差异，并且未找到一种细胞表面特异性标志物，因此目前鉴定神经干细胞主要有以下3个方面：特异性神经抗原的表达，包括巢蛋白、Musashi、转录因子及细胞黏附分子；自我更新能力，包括单细胞克隆分析、BrdU标记S期细胞；多向分化潜能，包括免疫细胞化学法、聚合酶链反应色法。
